i would like to inform your users, there is a gui tool in ubuntu for connecting.
goto synaptic and install gnome-ppp . you might have to put in the modem device manually.
Also once you have found the vendor id and device id, you can simply add the following to /etc/modules
usbserial vendor=0x19d2 product=0xfffd
the above is for the usb Zte MG880 modem from Reliance. Your vendor id and device id may differ. The usb modem should automatically be detected in subsequent boots

Hi
I’m new to Ubuntu and I tried to use Reliance Data card Model:EC325 for my internet connection. I followed the steps above.
the thing is i got a message stating that i dont have the previlages to edit the wvdial.config but i dont have any other user in unix there is only one user to it. user name is naveen. it didnt work.
can u plz tel me how can i use internet on ubuntu using reliance data card.

/etc/ppp/chap-secrets and /etc/ppp/pap-secrets do not have permission to be written by anyone except root. you could verify it using ‘ls -l /etc/ppp ‘

what you need to do is to run wvdial with root permissions, preferably using sudo,

e.g.

sudo wvdial /etc/wvdial.conf

alternately, you could change permissions of these files using chmod and make it writable by other users, which is dangerous though. if you do this, you should revert back permissions once you dial wvdial for the first time.

115200 is alright. that is the connection speed used for negotiations, but you wont actually get that speed. the actual bandwidth that you’ll get with this connection will be much lower than 115Kbps. even if you change those parameters, you wont see much difference.

if you want to check your bandwidth, use this tool http://www.speakeasy.net/speedtest . It would give you an accurate information on download and upload speeds. You could ofcourse try bumping the connection speed to the above numbers, and let me know if that really boosts your speed :) , chances of which are rare in my opinion.

Hi Gourav and Roman,
I got a very similar authentication problem that I cannot find a way out. There is no problem connecting to the provider using the same account from XP. Any ideas are welcome and appreciated.
The output follows:

Hi Gourav. Merry christmas and happy new year.
I have used Internet many hours, days; without problems. But now, I can not connect anymore.
PPP daemon has died = A modem hang up the phone (exit code = 16). Var/log/messages = warning: secret file /etc/ppp/papsecrets has world and/or group access. Please, can u help me to reconnect ?

Hi Gourav after 15 days, I have always the same problem. I have done what u tall me about permissions. sudo su, chmod a- …, u+ … ;
they’re rw for user only for pap-secrets. But I can not connect. A modem hang up the phone exit code = 16. plz, can u help me ?

I am on Ubuntu Meerkat edition. Simply plugged in my huwei stick, opened network connections. And used the tab ‘add new mobile broadband’. And Ubuntu took care of rest of details. (It gave me to choose my service provider from a list of indian mobile broadband operators). I just had to punch in my reliance HSD number.
